Simone Biles is the biggest name at the Tokyo Olympics and following the qualification round, she was in position to medal in as many as six events. But she surprised the world by dropping out of the women's team competition after her first apparatus, indicating she was not in the right headspace.
Hours later, it was announced she would not defend her gold medal in the individual all-around. Jade Carey will take her spot, joined by Suni Lee for the Americans.
It's not clear yet if Biles will take part in the four individual event finals.
Gymnastics events will happen in the evening hours in Tokyo, which means early in the morning in the U.S. All gymnastics events are being livestreamed and will be replayed on TV during NBC's primetime coverage.
Here is when you will may be able to see Biles and the U.S. women's gymnasts compete.
Women's Gymnastics Individual All-Around
Thursday, 6:50 a.m. ET
There will be a new women's Olympic all-around champion.
The individual apparatus finals will be spread out over three days during the second week of competition. They will happen in conjunction with the six men's apparatus finals.
Women's Gymnastics Vault Final
Sunday, Aug. 1, 4:55 a.m. ET
Watch for Biles to perform her new vault, the Yurchenko Double Pike if she competes. She's expected to win and teammate Jade Carey is a strong medal contender.
Women's Gymnastics Uneven Bars Final
Sunday, Aug. 1, 6:27 a.m. ET
The International Gymnastics Federation's two-per country rule saved Biles here. She finished 10th in qualifying, but four Russian gymnasts finished in the top four. Because of that, two of the Russians have to sit out, moving Biles into the final spot. Teammate Suni Lee qualified second, giving the U.S. two shots at gold, but it's well known that this is Biles' weakest event.
Women's Gymnastics Floor Final
Monday, Aug. 2, 5:00 a.m. ET
Biles has been so good on floor in her career, she has two moves named after her. She's the favorite to win even after a rough qualifying round.
Women's Gymnastics Balance Beam Final
Tuesday, Aug. 3, 4:48 a.m. ET
Biles won silver in this event at the 2016 Olympics in Rio. But this is not her strongest event as she finished 7th in qualifying. Suni Lee will join her for the Americans.
